Abstract

PROBLEM TO BE SOLVED: To improve function by kneading a foaming body of glass particles with adhesive so as to pressure-mold into a plate, and if necessary, integratedly interposing a porous sheet material, a metallic plate, or the like. SOLUTION: This plate for building 1 is constituted so that a foaming body of glass particles is kneaded with adhesive, and pressure-molded at fixed density. At request, a sheet-like reinforcing material such as wire net 3 is integratedly fitted to the surface part and/or the intermediate part. For the sheet-like reinforcing material, except the wire net 3, a net-like, lath-like, punching metal-like, or the like porous body is used. If necessary, the surface part and the side part of the plate 1 are integratedly covered with metal plate. Hereby, glass waste can be utilized so as to reduce cost, the weight can be reduced, the characteristics such as heat insulation, sound absorption, hygroscopicity, noncombustibility, can be held, and the strength can be improved by using together with a reinforcing material.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building board that can be used as a flooring material, a wall material, a ceiling material or a roofing base material, and more particularly to a building board suitable for a flooring material.

[0002]

2. Description of the Related Art Conventionally, there have been various construction boards made of various materials, for example, wood board, wood wool board, synthetic resin foam molding board, ALC board, etc., which are formed into desired thickness. It is used as a floor material, wall material, ceiling material or roof base material.

[0003]

The construction board made of the above-mentioned materials has a high material cost, and none of the materials themselves satisfy the characteristics such as light weight, heat insulation, sound absorption, moisture absorption, non-combustibility, etc.
Only some of the above characteristics were provided, and further improvement was required as a building board.

As a result of diligent efforts, the present inventor has made effective use of waste glass material, particularly as a floor material or other construction board, at low material cost, light weight, and heat insulating property. Therefore, it was possible to produce a plate body having a desired strength with characteristics of sound absorption, hygroscopicity, and nonflammability.

[0005]

[Means for Solving the Problems] A building board which is obtained by kneading a foam of glass particles with an adhesive and pressure-molding the same, and for improving the strength, a sheet is formed on the surface and / or the middle of the board. -Shaped reinforcing material may be integrally formed, and may be a metal sheet such as a steel plate, an aluminum plate, and a stainless plate. The metal-made metal plate may have a mesh shape, a net shape, a lath shape, a punching metal shape, or the like. It can be a sheet. Alternatively, an inorganic material such as glass fiber can be applied. In addition, if necessary, the surface portion and the side surface portion of the molded plate can be integrally covered with a metal plate. You may form a connection piece in the circumference in consideration of workability. It is free to stack linoleum and other decorative plates as finishing materials on the surfaces of the above various plates.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A foamed body of glass particles made from a waste glass material has a particle size of 1 mm or less to several millimeters. Specifically, 0.5
From the millimeters to 3 millimeters, those having an appropriate size can be selected in an appropriate mixing ratio. A mixture obtained by kneading these with an adhesive (including a binder) is pressure-molded in a frame and dried by heating, natural drying, or normal temperature drying to obtain a molded body having a desired density. The size and thickness may be set appropriately.

The glass particle foam is lightweight, has a heat insulating property, and is sound absorbing, moisture absorbing, and non-flammable, but since these are bonded with an adhesive, voids exist between the bonding of the particles. , It has a porosity, and also acts as a lightweight, heat insulating, sound absorbing, and hygroscopic property. Naturally, the degree of these changes depending on the size of the molding density.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of a building board according to the present invention, mainly showing floor materials. In FIG. 1, reference numeral 1 denotes a floor plate in which a foamed body of glass particles is kneaded with an adhesive, pressure-molded, and hardened to a predetermined density. The size is vertical, the horizontal length is 500
It is a square with a thickness of 35 mm. The weight is about 4100 grams. Steel plates 2 and 2 having a thickness of 0.5 to 0.8 mm are adhered and integrated on both surfaces thereof. The glass particle foam has a particle size of 0.5 mm to 1.5 mm and is appropriately mixed. When the steel sheet is not attached to the surface, the amount of deflection with respect to the load is large, but when the steel sheet is attached to one side or both sides, the amount of deflection is small and there is a reinforcing effect.
Therefore, if it is a wall material, a ceiling material, etc., it is not necessary to attach the steel plate.

FIG. 2 shows a wire mesh 3 in the middle of the expanded glass particle layer.
It is a plate body that is pressure-molded by interposing. This also has a so-called reinforcing effect of reducing deflection under load.

In FIG. 3, a flange is formed so as to project outwardly around a box body 4 of a metal plate, and the void is filled with a foamed body of glass particles kneaded with an adhesive, pressurized and dried to obtain a molded body. It is integrated with the box as 1. Further, the floor material is covered with a lid 5 made of a metal plate. Although the back surface of the lid is adhered to the molded body, pressure bonding may be used. Reference numeral 5a is a connecting piece, and the end portion of the lid body is caulked and fastened to the flange.

[0011]

[Effect] Since the building board of the present invention uses the waste material of glass, the material cost is reduced and it contributes to the prevention of pollution. Further, since the building board is a foamed body of glass particles, it has light weight, heat insulation, sound absorption, moisture absorption, and noncombustibility, and when it has a desired thickness, it retains strength and can be used for various applications described above. Further, as a reinforcing material, a metal plate, or a net, net, lath, punching metal,
The strength of the flooring (floor board) can be improved by interposing a sheet of other porous material on the surface of the molded body, or by interposing it in the middle part, or by covering with a metal box body and lid body, as a floor material (floor board). If it is used as another building board, it will be of great practical value.
